QR Payment Flow
QR payment flow defines how digital payment transactions move between customers, merchants, wallets, payment gateways, and financial institutions within EMVCo QR ecosystems.
Understanding QR Payment Flow
QR payment flow describes the end-to-end process of a QR payment transaction, from QR generation and scanning to payment authorization, routing, and settlement. EMVCo QR standards help standardize these workflows across interoperable payment ecosystems.
Depending on the payment model, QR payment flows may involve merchant-presented QR codes, consumer-presented QR codes, mobile wallets, issuing banks, acquiring institutions, payment gateways, interoperability networks, and fintech payment platforms.
Standardized payment flows improve interoperability, simplify merchant integration, and enable scalable digital payment acceptance across multiple financial ecosystems.
Typical Merchant QR Payment Flow
In Merchant Presented Mode (MPM), the merchant displays a QR code and the customer scans it using a wallet or payment application.
Merchant
Displays QR
Customer
Scans QR
Wallet
Processes request
Bank
Authorizes payment
Settlement
Transfers funds
Step-by-Step QR Transaction Process
QR Code Generation
The merchant or wallet system generates a QR payload containing payment-related information.
QR Scanning
The customer or merchant scans the QR code depending on the payment model.
Payload Interpretation
The payment application parses EMVCo QR payload data and extracts transaction information.
Payment Authorization
The issuing institution validates the payment request and authorizes the transaction.
Transaction Confirmation
The payment result is communicated back to the merchant and customer.
Settlement & Reconciliation
Financial settlement and reconciliation processes finalize the payment lifecycle.
Merchant Presented vs Consumer Presented Flow
Merchant Presented Mode
The merchant displays a QR code and the customer scans it using a payment application or mobile wallet.
Common in retail payments
Merchant displays QR
Customer scans merchant QR
Supports static & dynamic QR
Consumer Presented Mode
The customer generates or displays a QR code that the merchant scans using a POS or merchant application.
Wallet-generated QR
Merchant scans customer QR
Common in wallet ecosystems
Mobile-first payment model
Participants in QR Payment Ecosystems
